“…This can be explained by the energy transfer process from the Eu 3+ to Mn 2+ levels through nonradiative transitions to the excited 4 T 1 (G) state and emission to the ground 6 A 1 (S) state. It is possible that the Mn 2+ emission overlapped with the 5 D 0 → 7 F 0,1,3 Eu 3+ transition [56,57], which can be observed in the high-spectral-resolution PL spectra. Furthermore, the emission of Mn 2+ could be decreased through a concentration-quenching process.…”

A new series of Sr-based phosphates, Sr9−xMnxEu(PO4)7, were synthesized using the high-temperature solid-state method in air. It was found that these compounds have the same structure as strontiowhitlockite, which is a β-Ca3(PO4)2 (or β-TCP) structure. The concentration of Mn2+ ions required to form a pure strontiowhitlockite phase was determined. An unusual partial reduction of Eu3+ to Eu2+ in air was observed and confirmed by photoluminescence (PL) and electron spin resonance (ESR) spectra measurements. The PL spectra recorded under 370 nm excitation showed transitions of both 4f5d–4f Eu2+ and 4f–4f Eu3+. The total integral intensity of the PL spectra, monitored at 395 nm, decreased with increasing Mn2+ concentration due to quenching effect of Eu3+ by the Mn2+ levels. The temperature dependence of Eu2+ photoluminescence in a Sr9−xMnxEu(PO4)7 host was investigated. The conditions for the reduction of Eu3+ to Eu2+ in air were discussed.

“…Energy transfer between co-doped ions has been demonstrated to scale luminescence intensity. Energy transfer is important not only because it increases emission intensity but also because it allows lighting color tuning [1][2][3]. Several studies related to rare earths ions co-doped glasses have been attracting a great deal of interest [4][5][6].…”

High-quality Nd,Yb:YAG crystal with 5 at. % Yb3+ and 0.5 at. % Nd3+ was grown using the Czochralski method. A complete optical characterization was reported including absorption, excitation spectra and luminescence lifetime measurements at room temperature and emission spectra at temperatures ranging from 300 K to 800 K. The emission spectra of Nd3+/Yb3+ co-doped YAG were measured for different excitation wavelengths 808 nm and 940 nm. The presence of Yb3+ emission after excitation in the 4F5/2 and 4F3/2 levels of Nd3+ together with the 4I9/2→ 4F5/2 and 4I9/2→ 4F3/2 bands of Nd3+ in the excitation spectra of Yb3+ ions confirm that energy transfer occurs from Nd3+ to Yb3+. On the other hand, the back transfer from Yb3+ to Nd3+ can be neglected. This conclusion is also in agreement with the vanishing overlap between the Yb3+ emission and Nd3+ absorption. The analysis of the luminescence decay curves obtained after pulsed excitation has been used to further explore energy transfer processes and the interaction mechanism.
